HAY-STACKER.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed February 25, 1909. Serial No. 480,041.

To all whom it may concern:

Be it known that I, EDWARD G. CARTER, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Hay-Stackers, of whichthe following is a specification.

This invention relates to improvements in hay stackers, and has for itsobject the provision of a device of this class which will be efi'eotivefor quickly moving large loads, will be durable in wear, and willcomprise few and simple parts so that it may be economicallyconstructed.

The invention also has reference to resilient means used in connectionwith contact or stop-blocks, whereby the fork will be thrown in a mannerto impart a forward movement to the load at the time it is dischargedfrom the fork.

WVith these and other objects in view the invention consists of a novelcombination and arrangement of parts as described herein, pointed out bythe claims and as illustrated in the drawing, wherein,

Figures 1 and 2 are vertical, side views of the hay stacker, the forkbeing, respectively, in a lowered and raised position. Fig. 3 is a planview of the hay stacker, the fork being in a lowered position.

Referring now to the drawing for a more particular description, numeral1 indicates a frame upon which are mounted the movable parts of thestacker, and consists of the parallel side plates or skids 2 connectedand secured adjacent each other by the transverse end-plates 3 and 4 andintermediate crossplate 5.

I provide trusses 6, each comprising the vertical post 7 secured betweenthe terminals of the side plates, somewhat nearer the rear than thefront ends of said plates, and employ the pairs of truss plates 8 and 9extending from posts 7, respectively, to the rear and to points near thefront ends of plates 2 and secured to said plates; and braces 10 areused for sustaining posts 7, these braces being inclined and havingtheir outer ends secured near the top of posts 7,

upon truss-plates 9, their inner ends being secured upon cross-plate 5As thus de scribed frame 1 and parts thereon mounted may be convenientlydrawn from one field to another to places where hay is to be stacked,plates 2 operating as sleigh-runners, and by reason of the bracing asmentioned,

the parts are connected to reliably sustain the weight and stresses, asrequired.

I provide, the hay fork 11 constructed rigid with its movable arms 12,these arms being pivotally mounted at 13 upon and.

the hay to lesser or greater altitudes. The

fork comprises the series of tines 17 secured at their inner ends uponthe pair of strips 18, these strips being secured upon arms 12; strips18 are parallel and are spaced apart sufliciently to receivetherebetween the inner ends of the series of transverse tines 19. Tines17 are substantially in alinement with arms 12 and are held to positionsparallel with each other by reason of their mounting upon strips 18. Thetines 19 are held parallel with relation to each other by means of thecross strip 20 secured intermediate the ends of said tines, the innerends of these tines being secured upon tines 17. In operation, the forkswings upon its pivotal mounting from the position shown in Fig. 1 tothe position shown in Fig. 2, the tines 17 being at all times at anobtuse angle to the tines 19. The containing capacity of the fork, whilebeing loaded, is increased by this construction, and when the fork hasbeen completely elevated, the tines 19 have a downward inclination asshown in Fig. 2 which facilitates unloading. It will also be seen thatthe strips 18 operate to sustain each series of tines in their angularrelation, since they have bearings upon the tines 19 outwardly of themountings of said tines 19 upon tines 17.

I provide the pair of side-braces 21, each being mounted at one of theirends upon and near the front ends of arms 12, and they are extendeddivergently to fork 11, their opposite ends being mounted upon and nearthe outer ends of strips 18, and by reason of the divergence of thebraces, the fork, during its movements, is more firmly secured upon arms12. Braces 21 are adjustable as to length by means of bolts 22 seated inapertures 23 thereof, and when the length of arms 12 is changed as abovementioned, a corresponding change in length may be made of the braces.

For the purpose of elevating the fork, devices are employed, now to bedescribed. I

provide the V-shaped frame 40, having at its apex the rods 24 pivotallymounted there on at 45, and extended divergently therefrom to pivotalend-mountings 46 thereof upon arms 12, near strips 18. The ends of thedivergent arms 25 of frame 40 are pivotally mounted at 26 in brackets27, said brackets being secured upon the top of vertical posts 7. 1

I provide the standard or operating bar 28 of a length greater than thatof the V- shaped frame, and having its lower end pivotally mounted at 41in bracket 29, this bracket being secured upon and midway the length ofcross-plate 3. Link 42 is employed, having one of its ends pivotallymounted at 43 upon the upper terminal of the operating-bar, its oppositeend being pivotally mounted at 44L upon and at the apex of the V-shapedframe, and, from the description, it will be understood that a forwardlyswinging movement of the upper end of operating-bar 28 will cause aforward swinging movement of the upper end of the V-shaped frame, andthat the hay-fork will be elevated thereby since arms 12, by means ofrods 2t, are connected with the upper terminal of said V-shaped frame.

It will be noted that the hay-fork as shown, is unusually large incomparison with other parts, and this is a desired feature. Since theweight of the load is divided and sustained by the parts, as described,unusually large loads may be elevated, as will presently be seen, in thedescription of operation.

To operate the stacker, a pulley 30 may be mounted upon the outer end ofoperatingbar 28. Pulleys 31 and 32 are mounted upon and midway ofcross-plate 4. A cable or rope 33 may be secured upon the outer end ofbar 28, and from thence passed to engage the respective pulleys 31, 30and 32, and power from any suitable exterior source may be employed formoving the cable and to, thereby, elevate the fork, the lowering thereofbeing effected by gravity.

In operation, tines 17, while hay is placed thereon rest upon theground, and, of course, are horizontal; and at this time the front endof frame 1 is adjacent the stack to be formed. It will be understoodthat, during the upward swinging movement of the hayfork, the weight ofthe load rests upon tines 17. As soon, however, or just before the forkreaches its greatest altitude, tines 19 are substantially horizontal andthe weight rests thereon. At this time the front side of arms 12 engagethe contact-blocks 34 which are secured upon and extend upward from thefront ends of plates 2, and operate as stoplugs to prevent any furtherforward movement of these arms or of the fork. To the end, however, thatthe load may be thrown forwardly as far as possible at the time itleaves the fork, and to the end that a backward or return movement beimparted to arms 12, resilient means are employed, reliable inoperation, for the above purposes, said means comprising the rod 35disposed parallel with and secured upon cross-plate 4, as by clips 36and having its ends extended upward to form engagingarms 37 withtransverse indexes 38 disposed upon the plane traversed by arms 12.Coiled springs 39 are employed, each having one of its ends mounted uponplate 9, its opposite end being mounted upon one of arms 37 The normalposition of arms 37 is an inclination inwardly or rearwardly of frame 1,and is held there from the force of the springs. When arms 12 areswinging forwardly they will forcibly engage indexes 38, and arms 37will be swung to a vertical position, being moved by said arms 12. Thesearms will, by the resilient force of the springs, be thrown reversely atthe moment said arms encounter blocks 34:, thereby tending to impart aforward movement of the load and for the purpose of throwing the loadforwardly from the fork, as far as possible.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is,-
